RE: Gas motor for ultra lite stick 120
Gentleman
I also have a Ultra Stick 120 size I'm running a 26 size gas engine on it.( size prop either 16"or 18" )
Especially because it is rear carb and the engine is on 3" spacers, I had to use a larger than I wanted ( sub C 6 voltbattery) in the tail to balance it though. Plenty of Power. Flies for 40 minutes on 20 oz of fuel @ 2.70 a gallon
The plane calls for a 180 4 stroke so;
Comparision 180 Saito (1.80 cu. inches) = 30 cc remember that and any other comparision is easy
